Updates for more flexible streaming options

[atjohns]

This update is designed to make streaming more flexible in scenarios where the bot is handling both streaming and non-streaming conversations. Turning streaming on at the Web UI will now trigger session attributes containing the dynamo table and API Gateway endpoint information, so fulfillment Lambdas can look for those parameters and decide whether the response needs to be streamed.

Other small changes

• Bring the Web UI up to speed on Node/NPM versions
• Change the browser targets for webpack.
• Make the copy function/icon a toggle controlled by a config property and center it to align with the feedback buttons.

Austin, would it be possible to get a couple changes? In templates/codebuild-deploy.yaml:

• The output parameter name on 1306 is incorrect.
• Could we get the whole api gateway web socket url as an output?

Thanks!

Hey @t-jones, yes I can fix that typo. the outputs here actually don't really matter anymore now that its all being passed to the config directly and the UI is passing that back to the bot. I think they could probably just be deleted unless you have a use case for needing them?

@atjohns you are correct. Thanks for reminding me part of the point of what you are doing is to support N clients. We'll get this from the session as you show in the example.
